REPORT DETAILS

Summary of Plant Status AmerenUE operated the Callaway Plant at near 100 percent until March 22, 2008, when a downpower to 62 percent was required to repair a main feedwater pump control-oil valve. The plant was restored to full power on March 23,

REACTOR SAFETY

Initiating Events, Mitigating Systems, Barrier Integrity, and Emergency Preparedness

1R01 Adverse Weather Protection

Winter Seasonal Readiness Preparations

a. Inspection Scope

The inspectors performed a review of the licensee's preparations for winter weather for selected systems, including conditions that could result from low temperatures. The inspectors reviewed the licensee's procedures affecting these areas. Examples of aspects considered in the inspectors' review included:

  • cold weather protection features, such as heat tracing;
  • space heaters and weatherized enclosures; and
  • instrument controller and alarm calibration programs.

During the inspection, the inspectors focused on plant specific design features and the licensee's procedures used to mitigate or respond to adverse weather conditions. Additionally, the inspectors reviewed the Final Safety Analysis Report (FSAR) and performance requirements for systems selected for inspection, and verified that operator actions were appropriate as specified by plant specific procedures. The inspectors also reviewed corrective action program items to verify that the licensee was identifying adverse weather issues at an appropriate threshold and entering them into their corrective action program in accordance with station corrective action procedures. The inspectors' reviews focused specifically on the following plant system:

  • February 20, 2008, Condensate storage tank cold weather preparations. Documents reviewed by the inspectors included:
  • Procedure OTN-QJ-00003, Condensate storage tank freeze protection control panel, Addendum 2, Revision 0. This inspection constitutes one seasonal adverse weather sample as defined in Inspection Procedure 71111.01.

b. Findings

No findings of significance were identified.

- 4 -1R04 Equipment Alignment (71111.04)

Quarterly Partial System Walkdowns

a. Inspection Scope

The inspectors performed partial system walkdowns of the following risk-significant systems:

  • January 15, 2008, Safety injection and charging systems (EM and BG) common suction header;
  • February 19, 2008, Containment spray system Train A while Train B was out of service for planned modifications; and
  • March 18, 2008, Emergency diesel generator system Train A while Train B was out of service for emergent fuel oil leak repairs. The inspectors selected these systems based on their risk significance relative to the reactor safety cornerstones at the time they were inspected. The inspectors attempted to identify discrepancies that could impact the function of the system, and, therefore, potentially increase risk. The inspectors reviewed applicable operating procedures, system diagrams, FSAR, Technical Specification requirements, outstanding work orders, condition reports, and the impact of ongoing work activities on redundant trains of equipment in order to identify conditions that could have rendered the systems incapable of performing their intended functions. The inspectors also walked down accessible portions of the systems to verify components and support equipment were aligned correctly and were operable. The inspectors examined the material condition of the components and observed operating parameters of equipment to verify that there were no obvious deficiencies. The inspectors also verified that the licensee had properly identified and resolved equipment alignment problems that could cause initiating events or impact the capability of mitigating systems or barriers and entered them into the corrective action program with the appropriate significance characterization. Documents reviewed are listed in the attachment. These activities constituted three partial system walkdown samples as defined by Inspection Procedure 71111.04.

b. Findings

No findings of significance were identified.

1R05 Fire Protection

Routine Resident Inspector Tours (71111.05Q)

a. Inspection Scope

The inspectors conducted fire protection walkdowns which were focused on availability, accessibility, and the condition of firefighting equipment in the following risk-significant plant areas:

- 5 -* January 25, 2008, Auxiliary feedwater pump valve compartment Rooms 1304, 1324, and 1337, Area A-29;

  • February 1, 2008, Reactor trip switchgear Room 1403, Area A-27;
  • March 5, 2008, Battery Rooms 3403, 3404, 3405, and 3410 (south), Area C-15;
  • March 5, 2008, Class 1E air conditioning equipment Room 3415, Area C-13;
  • March 18, 2008, Main control room including behind panel Rooms 3601 and 3603-3606, Area C-27. The inspectors reviewed areas to assess if the licensee implemented a fire protection program that adequately controlled combustibles and ignition sources within the plant; effectively maintained fire detection and suppression capability; maintained passive fire protection features in good material condition; and implemented adequate compensatory measures for out of service, degraded or inoperable fire protection equipment, systems, or features in accordance with the licensee's fire plan. The inspectors selected fire areas based on their overall contribution to internal fire risk as documented in the plant's Individual Plant Examination of External Events with later additional insights, their potential to impact equipment which could initiate or mitigate a plant transient, or their impact on the plant's ability to respond to a security event. Using the documents listed in the attachment, the inspectors verified that fire hoses and extinguishers were in their designated locations and available for immediate use; that fire detectors and sprinklers were unobstructed; that transient material loading was within the analyzed limits; and fire doors, dampers, and penetration seals appeared to be in satisfactory condition.

These activities constituted six quarterly fire protection inspection samples as defined by Inspection Procedure 71111.05.

b. Findings

No findings of significance were identified.

1R06 Flooding

Internal Flooding

a. Inspection Scope

The inspectors reviewed selected risk-significant plant design features and licensee procedures intended to protect the plant and its safety-related equipment from internal flooding events. The inspectors reviewed flood analyses and design documents, including the FSAR, engineering calculations, and abnormal operating procedures for licensee commitments. The inspectors reviewed licensee drawings to identify areas and equipment that may be affected by internal flooding caused by the failure or misalignment of nearby sources of water. The inspectors also reviewed the licensee's corrective actions for previously identified flood-related items. The inspectors performed a walkdown of the following plant area to assess the adequacy of any watertight doors

- 6 -and verify drains and sumps were clear of debris and operable, and that the licensee complied with its flooding related commitments:

b. Findings

No findings of significance were identified.

1R11 Licensed Operator Requalification Program

Resident Inspector Quarterly Review (71111.11Q)

a. Inspection Scope

On March 5, 2008, the inspectors observed a crew of licensed operators perform a cooldown and depressurization following a loss of coolant accident in the plant's simulator to verify that operator performance was adequate, evaluators were identifying and documenting crew performance problems, and training was being conducted in accordance with licensee procedures. The inspectors evaluated the crew in the following areas:

  • licensed operator performance;
  • crew clarity and formality of communications;
  • ability to take timely actions in the conservative direction;
  • prioritization, interpretation, and verification of annunciator alarms;
  • correct use and implementation of abnormal and emergency procedures;
  • control board manipulations;
  • oversight and direction from supervisors; and
  • ability to identify and implement appropriate Technical Specification actions and Emergency Plan actions and notifications. The crew's performance in these areas was compared to pre-established operator action expectations and successful critical task completion requirements. This inspection constitutes one quarterly licensed operator requalification program sample as defined in Inspection Procedure 71111.11.

- 7 -b. Findings No findings of significance were identified.

1R12 Maintenance Effectiveness

a. Inspection Scope

The inspectors evaluated degraded performance issues involving the following risk-significant systems:

  • February 4, 2008, Train B service water pump discharge valve failed to open, Callaway Action Request (CAR) 200800829; and
  • March 5, 2008, Auxiliary building emergency exhaust system Damper GFD0025 found inoperable, CAR 200800878. The inspectors reviewed events such as where ineffective equipment maintenance has resulted in valid or invalid automatic actuations of risk-important systems and independently verified the licensee's actions to address system performance or condition problems in terms of the following:
  • implementing appropriate work practices;
  • identifying and addressing common cause failures;
  • scoping of systems in accordance with 10 CFR 50.65(b) of the maintenance rule;
  • characterizing system reliability issues for performance;
  • charging unavailability time;
  • trending key parameters for condition monitoring;
  • verifying appropriate performance criteria for structures, systems, and components/functions classified as (a)(2) or appropriate and adequate goals and corrective actions for systems classified as (a)(1). The inspectors assessed performance issues with respect to the reliability, availability, and condition monitoring of the system. The inspectors verified maintenance effectiveness issues were entered into the corrective action program with the appropriate significance characterization. Documents reviewed are listed in the attachment. This inspection constitutes two quarterly maintenance effectiveness samples as defined in Inspection Procedure 71111.12.

- 8 -b. Findings No findings of significance were identified.

1R13 Maintenance Risk Assessments and Emergent Work Control

a. Inspection Scope

The inspectors reviewed the licensee's evaluation and management of plant risk for the maintenance and emergent work activities affecting risk-significant and safety-related equipment listed below to verify that the appropriate risk assessments were performed prior to removing equipment for work:

  • January 14, 2008, Elevated risk due to a planned outage on offsite power line entering the switchyard;
  • January 30, 2008, Elevated risk due to Job P693757.500 on Valve EJV0156 affecting the Train A charging, safety injection, and residual heat removal pumps;
  • February 1, 2008, Elevated risk due to Job 0800755 emergent failure associated with the Train A reactor trip breaker;
  • February 12, 2008, Elevated risk due to emergent work on the turbine-driven auxiliary feedwater system (Jobs 07514088 and 06522794);
  • February 29, 2008, Elevated risk due to emergent work to repair jacket water leaks on the Train B emergency diesel generator (Job 08001231); and
  • March 24, 2008, Elevated risk due to emergent work to replace the Train A emergency diesel generator, cylinder number seven fuel oil return nipple. These activities were selected based on their potential risk significance relative to the reactor safety cornerstones. As applicable for each activity, the inspectors verified that risk assessments were performed as required by 10 CFR 50.65(a)(4) and were accurate and complete. When emergent work was performed, the inspectors verified that the plant risk was promptly reassessed and managed. The inspectors reviewed the scope of maintenance work, discussed the results of the assessment with the licensee's probabilistic risk analyst or shift technical advisor, and verified plant conditions were consistent with the risk assessment. The inspectors also reviewed Technical Specification requirements and walked down portions of redundant safety systems, when applicable, to verify risk analysis assumptions were valid and applicable requirements were met. Documents reviewed by the inspectors included:
  • Procedure EDP-ZZ-01129, Callaway Plant Risk Assessment, Revision 14 These activities constituted six samples as defined by Inspection Procedure 71111.13.

- 9 -b. Findings No findings of significance were identified.

1R15 Operability Evaluations

a. Inspection Scope

The inspectors reviewed the following issues:

  • January 17, 2008, CAR 200800367, Breaker NK5423 following the discovery of elevated temperatures on the breaker feeding 120 volt instrument Bus 114;
  • January 23, 2008, CAR 200800461, Train A and B containment recirculation sumps following discovery of a non-conforming strainer support plate construction;
  • March 18, 2008, CAR 200802019, Train B emergency diesel generator fuel oil leak. The inspectors selected potential operability issues based on the risk significance of the associated components and systems. The inspectors evaluated the technical adequacy of the evaluations to ensure that Technical Specification operability was properly justified and the subject component or system remained available such that no unrecognized increase in risk occurred. The inspectors compared the operability and design criteria in the appropriate sections of the Technical Specifications and FSAR to the licensee's evaluations, to determine whether the components or systems were operable. Where compensatory measures were required to maintain operability, the inspectors determined whether the measures in place would function as intended and were properly controlled. The inspectors determined, where appropriate, compliance with bounding limitations associated with the evaluations. Additionally, the inspectors also reviewed a sample of corrective action documents to verify that the licensee was identifying and correcting deficiencies associated with operability evaluations.

Documents reviewed are listed in the attachment. This inspection constitutes six samples as defined in Inspection Procedure 71111.15.

- 10 -b. Findings Containment Recirculation Sump Operability

Introduction.

An unresolved item was identified when several operability determinations, from January 22 through March 26, 2008, associated with the already installed containment recirculation sump strainer modification, were required to ensure new design discoveries did not create unacceptable reductions in margin to net positive suction head requirements for essential core cooling components.

Description.

10 CFR Part 50, Appendix B, Criterion III, requires, in part, that measures be established to assure that applicable regulatory requirements and design basis be correctly translated into specifications, drawings, procedures and instructions. Technical Specifications 3.5.2 and 3.6.6 require that residual heat removal and containment spray system components remain operable. Contrary to this, measures were not adequate to assure the design basis calculation of strainer head loss for the modification to the containment recirculation sump was correct. Several operability determination reviews failed to uncover additional design issues that were later discovered. AmerenUE identified that associated vendor calculation, TDI-6002-05, for clean strainer head loss omitted the head loss component associated with the orifices located in the strainer support plate. The size of the orifice beneath each strainer was not large enough to prevent head loss in excess of the net positive suction head required per the design conditions defined in the purchase specification supplied to the strainer vendor. The additional head loss due to the calculation error was 2.28 feet. This resulted in net positive suction head required being less than net positive suction head available. AmerenUE performed three separate operability determination reviews to demonstrate that the head loss margin could be recovered. The initial operability determination, on January 22, 2008, addressed the smaller support plate orifice holes by using a separate vendor's flow analysis of the residual heat removal and containment spray piping systems to demonstrate lower flow and head losses than described in the FSAR. This operability determination determined the limiting case flow path was the hot leg recirculation flow path. Another operability review, on March 12, 2008, addressed a nonconservative temperature correction through the orifices. Subsequent to this, the licensee informed the NRC that additional nonconservative inputs were used in the January 22, 2008, flow analysis of the residual heat removal system. Additional analyses were performed to regain margin. This resulted in the limiting case flow path changing from hot leg recirculation to cold leg recirculation. At the completion of the inspection period, there were still unresolved questions about the assumptions and results associated with the software used for regaining net positive suction head margin. Initial reviews have determined that adequate margin still exists. However, these require additional inspection and, when completed, the inspection results will require significance determination. This issue is considered unresolved pending additional NRC review of AmerenUE operability determination calculations, Unresolved Item 05000483/2008002-01, "Containment Recirculation Sump Operability."

1R18 Plant Modifications

a. Inspection Scope

The inspectors reviewed the design adequacy of the listed modifications. This included verifying that the modification preparation did not impair the following: (a) in-plant

- 11 -emergency/abnormal operating procedure actions; (b) key safety functions; and (c) operator response to loss of key safety functions.

The inspectors verified that postmodification testing maintained the plant in a safe configuration during testing and that the postmodification testing established operability by: (a) verifying that unintended system interactions did not occur; (b) verifying that performance characteristics, which could have been affected by the modification, met the design bases; (c) validating the appropriateness of modification design assumptions; and (d) demonstrating that the modification test acceptance criteria had been met.

  • March 18, 2008, Modification MP-08-0006, Over temperature delta temperature circuit card/setpoint change. Documents reviewed are listed in the attachment.

These activities constituted two samples as defined by Inspection Procedure 71111.18.

b. Findings

No findings of significance were identified

1R19 Postmaintenance Testing

a. Inspection Scope

4OA2 Identification and Resolution of Problems

Cornerstones: Initiating Events, Mitigating Systems, Barrier Integrity, Emergency Preparedness, Public Radiation Safety, Occupational Radiation Safety, and Physical Protection

.1 Routine Review of Items Entered into the Corrective Action Program

a. Inspection Scope

As part of the various baseline inspection procedures discussed in previous sections of this report, the inspectors routinely reviewed issues during baseline inspection activities and plant status reviews to verify that they were being entered into the licensee's corrective action program at an appropriate threshold, that adequate attention was being

- 17 -given to timely corrective actions, and that adverse trends were identified and addressed. Attributes reviewed included: the complete and accurate identification of the problem; that timeliness was commensurate with the safety significance; that evaluation and disposition of performance issues, generic implications, common causes, contributing factors, root causes, extent of condition reviews, and previous occurrence reviews were proper and adequate; and that the classification, prioritization, focus, and timeliness of corrective actions were commensurate with safety and sufficient to prevent recurrence of the issue. Minor issues entered into the licensee's corrective action program as a result of the inspectors' observations are included in the attached list of documents reviewed. These routine reviews for the identification and resolution of problems did not constitute any additional inspection samples. Instead, by procedure they were considered an integral part of the inspections performed during the quarter and documented in Section 1 of this report.

b. Findings

No findings of significance were identified.

.2 Daily Corrective Action Program Reviews

a. Inspection Scope

In order to assist with the identification of repetitive equipment failures and specific human performance issues for follow-up, the inspectors performed a daily screening of items entered into the licensee's corrective action program. This review was accomplished through inspection of the station's daily condition report packages. These daily reviews were performed, by procedure, as part of the inspectors' daily plant status monitoring activities and, as such, did not constitute any separate inspection samples.

b. Findings

No findings of significance were identified.

.3 Selected Issue Followup Inspection

a. Inspection Scope

The inspectors selected the below listed issues for a more in-depth review. The inspectors considered the following during the review of AmerenUE's actions: (1) complete and accurate identification of the problem in a timely manner; (2) evaluation and disposition of operability/reportability issues; (3) consideration of extent of condition, generic implications, common cause, and previous occurrences; (4) classification and prioritization of the resolution of the problem; (5) identification of root and contributing causes of the problem; (6) identification of corrective actions; and (7) completion of corrective actions in a timely manner.

- 18 -Damper GFD0024. The inspectors identified that extent of condition inspections initiated by CARs 200601898 and 200601924 in March 2006 were not timely but did not rise to the level of a more than minor violation as no loss of system function occurred.

  • February 26, 2008, CAR 200801400, Application of Technical Specification Surveillance Requirement 3.0.2 for initial inservice comprehensive pump testing. The new testing became a requirement when the licensee adopted the ASME Code for Operation and Maintenance of Nuclear Power Plants, 2001 Edition with 2003 Addenda, in December 2005. The inspectors reviewed the licensee's application of a 25 percent grace period beyond the required 2-year frequency for the containment spray system pumps. The testing required a modification in the form of an additional recirculation line for the pumps to meet the new ASME pump flow test requirement. The NRC determined that, although the licensee's identification of the requirement was not timely, no violation of regulatory requirements occurred.
  • March 17, 2008, CAR 200802019, Historical fuel oil leaks on Train B emergency diesel return lines. The inspectors reviewed five repeat fuel oil leaks on the Train B emergency diesel generator. Each occurrence appeared to be due to cyclical fatigue failure at the Number 7 cylinder fuel oil return line. Each time prior to the March 2008 failure resulted in a repair without a cause evaluation to determine the cause of the fatigue failures. The NRC determined this issue to be a minor violation because no loss of emergency diesel function occurred. This issue has been addressed by the AmerenUE corrective action program. The above constitutes completion of three in-depth problem identification and resolution samples.

b. Findings

No findings of significance were identified.
